What gives a cubic curve its curves?
Can you form an equation for the cubic curve shown here?
If a curve has no stationary points, what does that tell you about its gradient function?
Does that help you to determine an equation for this graph?

Underground Mathematics is hosted by Cambridge Mathematics. The project was originally funded by a grant from the UK Department for Education to provide free web-based resources that support the teaching and learning of post-16 mathematics.
Visit the site at undergroundmathematics.org to find more resources, which also offer suggestions, solutions and teacher notes to help with their use in the classroom.
